Publication number: 20230108209Abstract: In a service mesh, back-pressure is applied and relieved as needed by a control mechanism which is applied between pairs of services to control the rate at which service requests are made from one of service to the other via monitoring hardware and/or software metrics. A proxy of one service is monitored to observe the rate at which it receives service requests from the other service. If it is observed that the monitored metrics have breached allowable limits, back-pressure is applied to reduce the rate at which the other proxy transmits these service requests. Through continued monitoring of the proxy, the back-pressure can be later relieved when appropriate by increasing the permitted request rate.Type: ApplicationFiled: October 5, 2021Publication date: April 6, 2023Inventors: Adam John Pilkington, GORDON DOUGLAS HUTCHISON, Timothy J. MITCHELL, Graham C. Charters

Patent number: 11621919Abstract: A computer system hosting (micro)services that uses a service mesh to govern communication between the services. The services include consumer services and an event stream service, the latter directing an event stream from a producer service to the individual consumer services. The control plane of the service mesh has the role of creating and removing service instances. Based on a specified event capacity that is to be provided by the consumer services collectively, the control plane manages service provisioning by estimating the current event capacity of the system. This is done by measuring the event capacities of each consumer service instance and summing them, from which any shortfall or excess of the current event capacity in relation to the specified event capacity can be determined. Consumer service instances are then added in case of a shortfall or removed in case of an excess as needed to avoid over or under-provisioning.Type: GrantFiled: September 2, 2021Date of Patent: April 4, 2023Assignee: International Business Machines CorporationInventors: Gordon Douglas Hutchison, Adam John Pilkington, Graham C. Charters, Timothy J. Mitchell
